PCR-based methods for identification of two Eteobalea species (Lepidoptera: Cosmopterigidae) used as biocontrol agents of weedy Linaria species (Scrophulariaceae)
Download2005
Pohl, G. R., McClay, A. S., Sperling, F. A. H., Mitchell, A.
Two European species of the genus Eleobalea Hodges are being tested as classical biological control agents for toadflax (Linaria spp.) in Canada. Permits for the release of these species apply only to an Italian population of E. serratella Treitschke and a Serbian population of E. intermediella...

Phylogenetic framework for Dioryctria (Lepidoptera: Pyralidae: Phycitinae) based on combined analysis of mitochondrial DNA and morphology
Download2005
Sperling, F. A. H., Du, Y., Roe, A. D.
Coneworms of the genus Dioryctria Zeller are important lepidopterous pests of conifer cones throughout the Holarctic region. Seventy-nine Dioryctria species are currently recognized and arranged into 11 species groups, but a globally unified classification of these species groups has not been...

Phylogeny of Nearctic Species of the Xylosteana Group of Archips Hübner (Lepidoptera: Tortricidae) Based on Combined Analysis of Morphological and Mitochondrial DNA Data Sets
Download2002
Sperling, F. A. H., Kruse, J. J.
Abstract: The Holarctic Archips xylosteana Group consists of at least 18 morphologically similar species in the Nearctic, three of which were synonymized with A. argyrospila by Razowski and subsequently returned to species status, two that were described since 1986 but are clearly related to A....

Population Structure and Gene Flow in the White Pine Weevil, Pissodes strobi (Coleoptera: Curculionidae)
Download2004
Sperling, F. A. H., Laffin, R. D., Langor, D. W.
Abstract: The white pine weevil, Pissodes strobi (Peck), is a major source of damage to young spruce and pine trees across North America. The species contains a substantial amount of genetic, morphological, and behavioral variation, and identification of patterns of genetic variation on a broad...

Population structure and phylogenetic relationships of Ceutorhynchus neglectus (Coleoptera: Curculionidae)
Download2005
Sperling, F. A. H., Dosdall, L. M., Laffin, R. D.
Ceutorhynchus neglectus Blatchley is a weevil that is native to, and widely distributed in, North America. It has life-history characteristics similar to its alien invasive congener, Ceutorhynchus obstrictus (Marsham), the cabbage seedpod weevil. Our study was undertaken to compare the population...

Abstract: I review reports on the genetic basis for species differences in the Lepidoptera. In the six best-studied species complexes, more than half of all ecological, behavioral, or physiological differences among species are controlled by X-linked genes. Because Lepidoptera have about 30 pairs...

Systematics of the Dioryctria abietella Species Group ( Lepidoptera : Pyralidae ) Based on Mitochondrial DNA
Download2008
Sperling, F. A. H., Roques, A., Dormont, L., Roux-Morabito, G., Stein, J., Gillette, N. E.
Abstract: Coneworms of the genus Dioryctria Zeller include several Serious pests of conifer seeds that are notoriously difficult to distinguish as species. We surveyed mitochondrial DNA variation within the abietella species group by sequencing 451 bp of cytochrome oxidase subunit 1 (COI) and 572...

Tracing an Invasion : Phylogeography of Cactoblastis cactorum ( Lepidoptera : Pyralidae ) in the United States Based on Mitochondrial DNA
Download2008
Sperling, F. A. H., Simonsen, T. J., Brown, R. L.
Abstract: The adventive cactus moth Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), a widely used biological control agent for Opuntia Mill. cacti, was detected in Florida in 1989. Since then, it has spread along the Atlantic and Gulf Coasts of southeastern United States, threatening...
